NORDYNE condensing furnaces must be installed with outdoor combustion air piped directly to the furnace. Codes refer to this type of installation as direct vent, or two pipe installation.

Provisions must be made for adequate supply of air for combustion and ventilation. For United States installations, the adequacy of air provisions can be determined by consulting

3.At the front-to-back of duct run (Area “A”), bend the duct tabs and secure them directly to the duct.

4.At Area “B”, bend the duct tabs up and back over, around the duct connector, (See Step 3).

5.Fold/form the duct flap against the side of the duct connector and attach as shown, (See Step 4). Use three (3) staples (minimum) on each duct flap OR, if a 2X block/joist is not provided, use two (2) sheet metal screws (minimum) on each duct flap. An alternate attachment method is acceptable, as long as the plenum is securely attached.

6.Tape the duct flap edges with an approved tape for a leak-free joint.

INSTALL FURNACE

a. Remove furnace outer door(s) and bottom fuel line knockout.

b. Place furnace onto duct connector and cen- ter with floor opening.

c.Slide onto mounting plate. (Bottom rear slots on furnace should engage with mounting plate tabs.)

d.Secure front with one (1) fastener at each corner (See Figure 13 or 14).

the current version of the National Fuel Gas Code (ANSI Z223.1/NPFA-54). For Canadian installations, requirements are specified in the National Standard of Canada (CAN/CGA B149.1 & .2). Consult local codes for special requirements.

NOTE: If the furnace is operated without adequate air for combustion and ventilation, it may not perform properly. Furnace components may be strained by high temperature and could fail prematurely.

!WARNING:

The combustion air piping must not be blocked or restricted in any manner.

!WARNING:

Furnace installation using methods other than those described in the following sections must comply with the National Fuel Gas Code and all applicable local codes to provide sufficient combustion air for the furnace.
